Key benefits

Key Benefits of the Hyde & Sleep Lime Hybrid Serene Foam King Size Mattress

  • Elbow room for two: At 75cm each you gain 7.5cm over a UK double, which means a stray knee or elbow is a little less likely to end up on your partner's side.
  • Length for taller sleepers: At 200cm, or 6ft 6in, it's 10cm longer than a UK double, so a taller partner can stretch out without their feet pressing against the end.
  • Easier for early risers: If one of you gets up hours before the other, the extra width gives slightly more distance between you, so the early riser can slip out without climbing past their partner.
  • Space for pregnancy pillows: During pregnancy and the months after, a long support pillow fits alongside you without pushing your partner towards the edge.
  • A modest step up in room size: We suggest a bedroom of at least 2.7m x 2.9m, only slightly more than the 2.6m x 2.8m we'd allow for a UK double.

Who should buy the Hyde & Sleep Lime Hybrid Serene Foam King Size Mattress?

This size suits you if...

You share the bed every night and keep drifting into each other in a UK double, or one of you is near six foot and wants to lie flat without curling up. It also fits if your schedules differ and the early riser needs room to get out without disturbing the other person.

Consider another size if...

Your bedroom is smaller than our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Hyde & Sleep Lime Hybrid UK king big enough for two people?

For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more each than the UK double. If you both sprawl, or a dog regularly joins you, the UK super king gives 90cm each. That is 15cm more each than the UK king, but we suggest at least 3m x 2.9m for it.

How much bigger is a UK king Lime Hybrid than a double?

The UK king is 15cm wider and 10cm longer than the UK double. The width difference sounds small on paper, but spread across two sleepers it means 7.5cm more each. The extra length is the change taller partners tend to notice first.

Is the Lime Hybrid in a UK king long enough for tall people?

At 200cm (6ft 6in), the UK king is 10cm longer than the UK double, the UK small double and the UK single. If one of you is close to six foot, this extra length is often the main reason to size up. The UK super king is the same length, so it only adds width.

What size bedroom do I need for a Hyde & Sleep Lime Hybrid king?

We suggest at least 2.7m x 2.9m, and 3.2m x 3.2m feels comfortable. New build master bedrooms can feel smaller once fitted wardrobes are in, so measure the floor space you actually have, then compare the retailers listed on this page.

What bedding fits a UK king Lime Hybrid mattress?

Standard UK king sheets fit the 150 x 200cm surface, and a 230 x 220cm king duvet gives two sleepers enough to share. The mattress is 27cm deep, so check that your fitted sheets have deep enough pockets to tuck in properly.
